September 1999 Preface This Technical Information Manual provides information for the IBM PC 300 Types 6584 and 6594. It is intended for developers who want to provide hardware and software products to operate with these IBM computers and provides an in-depth view of how these IBM computers work. Users of this publication should have an understanding of computer architecture and programming concepts.

Terminology usage Attention: The term reserved describes certain signals, bits, and registers that should not be changed. Use of reserved areas can cause compatibility problems, loss of data, or permanent damage to the hardware. When the contents of a register are changed, the state of the reserved bits must be preserved. When possible, read the register first and change only the bits that must be changed. In this manual, some signals are represented in a small, all-capital-letter format (-ACK). A minus sign in front of the signal indicates that the signal is active low. No sign in front of the signal indicates that the signal is active high. The use of the term hex indicates a hexadecimal number. Copyright IBM Corp. September 1999 vii When numerical modifiers such as K, M, and G are used, they typically indicate powers of 2, not powers of 10. For example, 1 KB equals 1 024 bytes (2 10), 1 MB equals 1 048 576 bytes (2 20), and 1 GB equals 1 073 741 824 bytes (230). When expressing storage capacity, MB equals 1 000 KB (1 024 000).

System board features This section includes information about system board features. For an illustration of the system board, see “System board, Types 6584 and 6594” on page 13. Pentium III microprocessor with MMX technology PC 300PL Types 6584 and 6594 come with an Intel Pentium III microprocessor. The microprocessor, which has an attached heat sink, plugs directly into a connector on the system board. Features The features of this microprocessor are as follows: Optimization for 32-bit software 64-bit microprocessor data bus 133 MHz front side bus (FSB) 256 KB L2 cache integrated into the microprocessor 32-bit microprocessor address bus Math coprocessor MMX technology, which boosts the processing of graphic, video, and audio data Cache speed is half of processor core speed – 4-way set associative – Nonblocking L2 cache The Pentium III microprocessor provides 256 KB L2 cache. The L2 cache ECC function is automatically enabled if ECC memory is installed. If non-ECC memory is installed, the L2 cache ECC is disabled. (For information on overriding the ECC memory settings, see the chapter about the Configuration/Setup Utility program, in PC 300PL User Guide.) More information on this microprocessor is available at http://www.intel.com on the World Wide Web. Chip set control The Intel 820 chip set is the interface between the microprocessor and the following: 4 Memory subsystem PCI bus IDE bus master connection High-performance, PCI-to-ISA bridge USB ports SMBus Enhanced DMA controller Real-time clock (RTC) Copyright IBM Corp. September 1999 Chapter 2. System board features System memory The system memory interface is controlled by the Intel 820 chip set. Rambus dynamic random access memory (RDRAM) is standard. The maximum amount of addressable system memory is 1 GB. For memory expansion, the system board provides two Rambus inline memory module (RIMM) connectors. The system board also supports PC700 memory and PC800 memory RIMMs in sizes of 64 MB, 128 MB, 256 MB, and 512 MB. The amount of memory that is preinstalled varies by model. The following information applies to system memory: ECC or non-ECC RDRAM is standard. The maximum height of memory modules is 6.35 cm (2.5 in.). Each memory connector supports a maximum of 512 MB of memory, when available. Install only ECC RIMMS to enable ECC. If you use ECC and non-ECC memory together, all installed memory will function as non-ECC memory. RIMM connectors do not support dual inline memory modules (DIMMs). Any connector that does not have a RIMM installed must have a continuity RIMM (C-RIMM), a module that looks like a RIMM but has no memory on it. A continuity RIMM is used to continue the connection on a RIMM connector that does not have memory installed in it. Use PC700 or PC800 RIMMs only. Maximum system memory can be auto-detected and auto-configured using serial presence detect and configuration interface (BIOS specific). The following table shows the possible configuration of RIMMs and continuity RIMMs that can be used in the PC 300PL Personal Computer. Figure 1.

Chapter 2. System board features 5 Chapter 2. System board features PCI bus The fully synchronous 33 MHz PCI bus originates in the chip set. Features of the PCI bus are: Integrated arbiter with multitransaction PCI arbitration acceleration hooks Zero-wait-state, microprocessor-to-PCI write interface for high-performance graphics Built-in PCI bus arbiter with support for up to five masters Microprocessor-to-PCI memory write posting with 5-Dword-deep buffers Conversion of back-to-back sequential microprocessor-to-PCI memory write to PCI burst write PCI-to-DRAM posting 18 Dwords PCI-to-DRAM up to 100+ MB/sec bandwidth Multitransaction timer to support multiple short PCI transactions within one PCI ARB cycle PCI 2.2 compliant Delayed transaction PCI parity checking and generation support IDE bus master interface The system board incorporates a PCI-to-IDE interface that complies with the AT Attachment Interface with Extensions. The bus master for the IDE interface is integrated into the I/O hub of the Intel 820 chip set. The chip set is PCI 2.2 compliant. It connects directly to the PCI bus and is designed to allow concurrent operations on the PCI bus and IDE bus. The chip set is capable of supporting PIO mode 0–4 devices and IDE DMA mode 0–3 devices, ATA 66 transfers up to 66 megabytes per second (MBps). The IDE devices receive their power through a four-position power cable containing +5, +12, and ground voltage. When devices are added to the IDE interface, one device is designated as the master device and another is designated as the slave or subordinate device. These designations are determined by switches or jumpers on each device. There are two IDE ports, one designated Primary and the other Secondary, allowing for up to four devices to be attached. The total number of physical IDE devices is determined by the mechanical package. For the IDE interface, no resource assignments are given in the system memory or the direct memory access (DMA) channels. For information on the resource assignments, see “Input/output address map” on page 36 and Figure 38 on page 40 (for IRQ assignments). Two connectors are provided on the riser card for the IDE interface. For information on the connector pin assignments, see “IDE connectors” on page 30. USB interface Universal Serial Bus (USB) technology is a standard feature of the computer. The system board provides the USB interface with two connectors integrated into the ICH1 (I/O hub) in the chip set. A USB-enabled device can attach to a connector, and if that device is a hub, multiple peripheral devices can attach to the hub and be used by the system. The USB connectors use Plug and Play technology for installed devices. The speed of the USB is up to 12 MB/sec with a maximum of 127 peripheral devices. The USB is compliant with Universal Host Controller Interface Guide 1.0. 6 Technical Information Manual Chapter 2. System board features Features provided by USB technology include: Support for hot-pluggable devices Support for concurrent operation of multiple devices Suitability for different device bandwidths Support for up to five meters length from host to hub or from hub to hub Guaranteed bandwidth and low latencies appropriate for specific devices Wide range of packet sizes Limited power to hubs For information on the connector pin assignments for the USB interface, see “USB port connectors” on page 33. Low pin count bus The low pin count (LPC) bus allows a connection of the ISA and X-Bus devices such as Super I/O. The PC 300PL Personal Computer uses the National Semiconductor PC87360 Super I/O chip. The PC87360 chip includes the following: Floppy disk controller Keyboard and mouse controller IEEE 1284 parallel port Two UART serial ports Wake on LAN support General purpose input/output (GPIO) ports PC98 compliance ACPI compliance Diskette write protection can be enabled or disabled by a programmable setting in the LPC I/O.

This module, which supports Plug and Play, controls the following features: Diskette drive interface Serial port Parallel port Keyboard and mouse ports General-purpose I/O ports Diskette drive interface The PC 300PL Personal Computer has four drive bays for installing internal devices. The following is a list of devices that the diskette drive subsystem supports: 1.44 MB, 3.5-inch diskette drive 1.44 MB, 3.5-inch, 3-mode drive for Japan (no BIOS support for 3-mode drive) 1.2 MB, 5.25-inch diskette drive 1 Mbps, 500-Kbps, or 250 Kbps internal tape drive One connector is provided on the system board for diskette drive support. For information on the connector pin assignments, see “Diskette drive connector” on page 31. Serial ports Two universal asynchronous receiver/transmitter (UART) serial ports are integrated into the system board. The serial ports include 16-byte data, first-in first-out (FIFO) buffers and have programmable baud rate generators. The serial ports are NS16450 and PC16550A compatible. For information on the connector pin assignments, see “Serial port connector” on page 34. Note: Current loop interface is not supported. The following figure shows the serial port assignments in the configuration. Figure 4. Serial port assignments Port assignment Address range (hex) IRQ level Serial 1 03F8–03FF IRQ4 Serial 2 02F8–02FF IRQ3 Serial 3 03E8–03FF IRQ4 Serial 4 02E8–02FF IRQ3 The default setting for the serial port is COM1. Parallel port Integrated in the system board is support for extended capabilities port (ECP), enhanced parallel port (EPP), and standard parallel port (SPP) modes. The modes of operation are selected through the Configuration/Setup Utility program with the default mode set to SPP. The ECP and EPP modes are compliant with IEEE 1284. The following figure shows the parallel port assignments used in the configuration. 10 Technical Information Manual Chapter 2. System board features Figure 5. Parallel port assignments Port assignment Address range (hex) IRQ level Parallel 1 03BC–03BE IRQ7 Parallel 2 0378–037F IRQ5 Parallel 3 0278–027F IRQ5 The default setting for the parallel port is Parallel 1. The system board has one connector for the parallel port. For information on the connector pin assignments, see “Parallel port connector” on page 34. Keyboard and mouse ports The keyboard and mouse subsystem is controlled by a general purpose 8-bit microcontroller; it is compatible with 8042AH.

Cabling requirements for Wake on LAN adapters The PC 300PL Personal Computer has a 3-pin header on the system board that provides the Auxiliary 5 volts (AUX5) and wake-up signal connections. Newer Wake on LAN adapters have a single 3-pin header that connects to the 3-pin header on the riser card. Some Wake on LAN adapters have two headers: a 3-pin, right-angle header for AUX5, and a 2-pin straight header for the wake-up signal. These Wake on LAN adapter options include a Y-cable that has a 3-pin system board connector on one end and splits into the 3-pin and 2-pin connectors that connect to the adapter. Chapter 3. Physical specifications 17 Chapter 4. Power supply Chapter 4. Power supply The power-supply requirements are supplied by 145-watt PC 300PL Personal Computer power supply. The power supply provides 3.3-volt power for the Pentium microprocessor and core chip set and 5-volt power for PCI adapters. Also included is an auxiliary 5-volt (AUX 5) supply to provide power to power-management circuitry and a Wake on LAN adapter. The power supply converts the ac input voltage into four dc output voltages and provides power for the following: System board Adapters Internal drives Keyboard and auxiliary devices USB devices A logic signal on the power connector controls the power supply; the front panel switch is not directly connected to the power supply. The power supply connects to the system board with a 2 x 10 connector. Power input The following figure shows the power-input specifications. The power supply has a manual switch to select the correct input voltage. Figure 7.

Internal DASD Chapter 4. Power supply 19 Chapter 4. Power supply Note: Some adapters and hard disk drives draw more current than the recommended limits. These adapters and drives can be installed in the system; however, the power supply will shut down if the total power used exceeds the maximum power that is available. Output protection The power supply protects against output overcurrent, overvoltage, and short circuits. See the power supply specifications on the previous pages for details. A short circuit that is placed on any dc output (between outputs or between an output and dc return) latches all dc outputs into a shutdown state, with no damage to the power supply. If this shutdown state occurs, the power supply returns to normal operation only after the fault has been removed and the power switch has been turned off for at least one second. If an overvoltage fault occurs (in the power supply), the power supply latches all dc outputs into a shutdown state before any output exceeds 130% of the nominal value of the power supply. Connector description The power supply for the PC 300PL Personal Computer has four 4-pin connectors for internal devices. The total power used by the connectors must not exceed the amount shown in “Component outputs” on page 19. For connector pin assignments, see Appendix A, “Connector pin assignments” on page 25. 20 Technical Information Manual Chapter 5. System software Chapter 5. System software This section briefly describes some of the system software included with the computer. BIOS The computer uses the IBM basic input/output system (BIOS), which is stored in flash electrically erasable programmable read-only memory (EEPROM). Some features of the BIOS are: PCI support in accordance with PCI BIOS Specification 2.2 Microsoft PCI IRQ Routing Table Plug and Play support in accordance with Plug and Play BIOS Specification 1.1a Advanced Power Management (APM) support according to APM BIOS Interface Specification 1.2 Wake on LAN support Wake on Ring support Alert on LAN support Remote program load (RPL) and Dynamic Host Configuration Protocol (DHCP) Startable CD-ROM support Flash-over-LAN support Alternate startup sequence IBM look and feel, such as screen arrangements ACPI (Advanced Configuration and Power Interfaces) 1.0b IDE logical block addressing (LBA) support LSA 2.0 support LS120 support DM BIOS 2.1 (DMI 2.0 compliant) PC99 compliance Plug and Play Support for Plug and Play conforms to the following: Plug and Play BIOS Specification 1.1a and 1.0 Plug and Play BIOS Extension Design Guide 1.0 Plug and Play BIOS Specification, Errata, and Clarifications 1.0 Guide to Integrating the Plug and Play BIOS Extensions with system BIOS 1.2 Plug and Play Kit for DOS and Windows POST IBM power-on self-test (POST) code is used. Also, initialization code is included for the on-board system devices and controllers. POST error codes include text messages for determining the cause of an error. For more information, see Appendix D, “Error codes” on page 41. Copyright IBM Corp. September 1999 21 Chapter 5. System software Configuration/Setup Utility program The Configuration/Setup Utility program provides menus for selecting options for devices, I/O ports, date and time, system security, start options, advanced setup, and power management. More information on using the Configuration/Setup Utility program is provided in PC 300PL User Guide. Advanced Power Management (APM) The PC 300PL Personal Computer computers come with built-in energy-saving capabilities. Advanced Power Management (APM) is a feature that reduces the power consumption of systems when they are not being used. When enabled, APM initiates reduced-power modes for the monitor, microprocessor, and hard disk drive after a specified period of inactivity. The BIOS supports APM 1.2. This enables the system to enter a power-managed state, which reduces the power drawn from the ac electrical outlet. Advanced Power Management is enabled through the Configuration/Setup Utility program and is controlled by the individual operating system. For more information on APM, see PC 300PL User Guide and Understanding Your Personal Computer. Advanced Configuration and Power Interface (ACPI) Automatic Configuration and Power Interface (ACPI) BIOS mode enables the operating system to control the power management features of the computer. Not all operating systems support ACPI BIOS mode. See the operating system documentation to determine if ACPI is supported. Flash update utility program The flash update utility program is a stand-alone program to support flash updates. This utility program updates the BIOS code and can change the machine readable information (MRI) to different languages. The flash update utility program is available on a 3.5-inch diskette. Diagnostic program The diagnostic program that comes with the PC 300PL Personal Computer computer is provided on the Product Recovery CD and Device Driver and IBM Enhanced Diagnostics CD. It runs independently of the operating system. You can use IBM Enhanced Diagnostics to diagnose and repair problems with the computer. You can download the latest version from http://www.ibm.com/pc/support/desktop/desktop_support.html on the World Wide Web. For more information on this diagnostic program, see PC 300PL User Guide. 22 Technical Information Manual Chapter 6. System compatibility Chapter 6. System compatibility This chapter discusses some of the hardware, software, and BIOS compatibility issues for the computer. See the Compatibility Report for a list of compatible hardware and software options. Hardware compatibility This section discusses hardware, software, and BIOS compatibility issues that must be considered when designing application programs. Many of the interfaces are the same as those used by the IBM Personal Computer AT. In most cases, the command and status organization of these interfaces is maintained. The functional interfaces are compatible with the following interfaces: Intel 8259 interrupt controllers (edge-triggered mode) National Semiconductor NS16450 and NS16550A serial communication controllers Motorola MC146818 Time of Day Clock command and status (CMOS reorganized) Intel 8254 timer, driven from a 1.193 MHz clock (channels 0, 1, and 2) Intel 8237 DMA controller, except for the Command and Request registers and the Rotate and Mask functions; the Mode register is partially supported Intel 8272 or 82077 diskette drive controllers Intel 8042 keyboard controller at addresses hex 0060 and hex 0064 All video standards using VGA, EGA, CGA, MDA, and Hercules modes Parallel printer ports (Parallel 1, Parallel 2, and Parallel 3) in compatibility mode Use this information to develop application programs. Whenever possible, use the BIOS as an interface to hardware to provide maximum compatibility and portability of applications among systems. Hardware interrupts Hardware interrupts are level-sensitive for PCI interrupts. The interrupt controller clears its in-service register bit when the interrupt routine sends an End-of-Interrupt (EOI) command to the controller. The EOI command is sent regardless of whether the incoming interrupt request to the controller is active or inactive. The interrupt-in-progress latch is readable at an I/O-address bit position. This latch is read during the interrupt service routine and might be reset by the read operation or it might require an explicit reset. Note: For performance and latency considerations, designers might want to limit the number of devices sharing an interrupt level. With level-sensitive interrupts, the interrupt controller requires that the interrupt request be inactive at the time the EOI command is sent; otherwise, a new interrupt request will be detected. To avoid this, a level-sensitive interrupt handler must clear the interrupt condition (usually by a read or write operation to an I/O port on the device causing the interrupt). After processing the interrupt, the interrupt handler: 1. Clears the interrupt 2. Waits one I/O delay 3. Sends the EOI Copyright IBM Corp. September 1999 23 Chapter 6. System compatibility 4. Waits one I/O delay 5. Enables the interrupt through the Set Interrupt Enable Flag command Hardware interrupt IRQ9 is defined as the replacement interrupt level for the cascade level IRQ2. Program interrupt sharing is implemented on IRQ2, interrupt hex 0A. The following processing occurs to maintain compatibility with the IRQ2 used by IBM Personal Computer products: 1. A device drives the interrupt request active on IRQ2 of the channel. 2. This interrupt request is mapped in hardware to IRQ9 input on the second interrupt controller. 3. When the interrupt occurs, the system microprocessor passes control to the IRQ9 (interrupt hex 71) interrupt handler. 4. This interrupt handler performs an EOI command to the second interrupt controller and passes control to the IRQ2 (interrupt hex 0A) interrupt handler. 5. This IRQ2 interrupt handler, when handling the interrupt, causes the device to reset the interrupt request before performing an EOI command to the master interrupt controller that finishes servicing the IRQ2 request. Hard disk drives and controller Reading from and writing to the hard disk is initiated in the same way as in IBM Personal Computer products; however, new functions are supported. Software compatibility To maintain software compatibility, the interrupt polling mechanism that is used by IBM Personal Computer products is retained. Software that interfaces with the reset port for the IBM Personal Computer positive-edge interrupt sharing (hex address 02Fx or 06Fx, where x is the interrupt level) does not create interference. Software interrupts With the advent of software interrupt sharing, software interrupt routines must daisy chain interrupts. Each routine must check the function value, and if it is not in the range of function calls for that routine, it must transfer control to the next routine in the chain. Because software interrupts are initially pointed to address 0:0 before daisy chaining, check for this case. If the next routine is pointed to address 0:0 and the function call is out of range, the appropriate action is to set the carry flag and do a RET 2 to indicate an error condition. Machine-sensitive programs Programs can select machine-specific features, but they must first identify the machine and model type. IBM has defined methods for uniquely determining the specific machine type. The machine model byte can be found through Interrupt 15H, Return System Configuration Parameters function (AH)=C0H). 24 Technical Information Manual Appendix A. Connector pin assignments Appendix A.
